摘　　要：传统风偏角的计算模型没有考虑气象因素对空气密度的影响,文中分析了气象因素对风偏角的影响,提出了基于气象的风偏角计算模型,提出了2种分析风偏角与气象要素关系的数学模型。最后通过气象实例数据,对风偏角进行了仿真计算,并用数学模型对风偏角及其影响因素数据进行了建模分析,同时对风偏角进行了预测。结果表明,风速、风向、相对湿度、气压、气温是影响风偏角的主要气象因素,提出的数学模型能较好地分析了风偏角与其影响因素之间的关系,并且具有较高的风偏角预测精度。Traditional windage yaw angle calculation model does not consider the impact of meteorological factors on air power density. This paper analyzes the influencing of meteorological factors on the windage yaw angle, and proposed a calculating model of windage yaw angle based on meteorological. And proposes two mathematical models to analyze the relationship between windage yaw angle and meteorology factors. Finally, simulates windage yaw angle by examples of meteorological data, and predicts windage yaw angle with modeling analysis the meteorological factors. The results show that wind speed, wind direction, relative humidity, air pressure, air temperature is the main influence factors of windage yaw angle. The proposed mathematical models can analyze better the relationship between windage yaw angle and their impacted factors, and has a high precision in windage yaw angle prediction.
